Does anyone know if the black tank rinse has a built in back flow preventer? Should this be a concern? I'm not as worried about my water hose, as it's dedicated for the task, but I am concerned about the water supply where I hook up to.


Also regarding the sewer hose (the big 3" hose). I am getting rid of the supplied hose for a better quality, and longer one. What length hose do you all use? The factory hose was just barely long enough for more than a few times, but I don't want miles of the stuff either...  Thanks.

Yes the black tank has a check valve inline and I use the water hose they gave me with the Oliver for the Black Tank and have a 10 & 25 foot Blue Fresh water hose that we use, I like it better but it is just harder to roll up in really cold weather gets much stiffer. Thanks Gary
